I SUPPLEMENTARY TRUCK-FRAME FOR BRAKE MECHANISM.

SPECIFICATION forming part of Letters Patent No. 772,946, dated Oetober25, 1904. Application filed February 19, 1903. Serial No. 144,066. (No model.)

T0 to whom it may concern:

Be it known that I, WILLIAM GORDON MAC- LAUGHLIN, a citizen of the United States, re-

anism;- and I do declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and-use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to an auxiliary cradle or frame adapted to be attached to the truckframe of cars and to support the air-brake of which the cars are controlled. r

The object of the invention is to provide means for mounting the brake mechanism directly upon an extension of the truck-frame,

so that the working parts of the brake may be securely fixed in a manner to prevent change in their relative positions, overcoming the objection which heretofore has been encountered where a portion of the brake mechanism has been mounted upon the truck-frame and a portion upon the body of the car. In single-truck cars the relative movement between the car-body and the truck-frame is such as to render impossible the perfect working of the brake mechanism where portions of the operative parts are mounted upon the truck-frame and car-body. i

The above object is attained and the difliculties mentioned overcome by the formation ism.

designates the side bars of the truck-frame.

To the ends of these side bars are bolted at 2 the channel-irons 3, which form the sides of the auxiliary frame or cradle, the outer ends of said channel-irons being connected by the cross channel-iron 1 through the medium of Crossing between the I the-corner-brackets 5.

side irons?) are the transverse channel-iron bars 6 and 7, which are bolted at their ends to the flanges of the side irons.

Supported upon the cross-bars 6 and? is the main air-reservoir, into which air is pumped from a suitable compressor. (Not shown.) The cross-bars 6 and 7 at thepoint,

where the main reservoir is supported thereon are curved downwardly, as at 9, to form a seat for said reservoir and at the same time depress it sufficiently to allow it to be mounted without coming in contact with the carbody. Suitable straps 10 are passed around said reservoir and bolted to the cross-bars to embrace the upper arc of said reservoir and are bolted. at 13 to the cross-bars 6 and 7 The brake-cylinder 14 is mounted upon the bars 7 of the-frame and is adapted to receive air from the auxiliary cylinder through a suit able pipe, (not shown,) said cylinder being secured in place by the metal straps 15, which are bolted to said bars. The piston-rod 16, extending from said cylinder, is provided on the outer end thereof with a funnel-shaped hood 17 which is adapted to loosely fit over the end of the push-rod 18, mounted in a suitable guide 19, which is secured to the bars of the frame and through which said push-rod is adaptedto reciprocate. Pivoted at 20' to the push-rod is a lever 21, which is fulcrumed at 22 and pivoted at 23 to a connecting-bar 24, which is in turn pivoted to thebrake-lever 25, adapted to be connected with the brake mechanism. (Not shown.) .To one end of the brake-lever is attached a rod 26, adapted to flexibility thereto.

lead to the hand-brake, whereby provision is made for braking the car by hand when necessary. Mounted in and uniting the divisions of the connecting-bar is a link 27, which adds When the piston rod moves outwardly, the funnel-shaped hood engages the end of the push-rod 18 and operates said rod to apply the brakes, as will be understood. The flaring opening in the hood always insures the entrance of the push-rod therein and obviates any binding of said parts should the springing of the frame cause the piston and push-rod to stand out of axial alinement.

It will now be understood that by means of this cradle or supplementary frame, which may be attached to the side bars of the ordinary truck frame, provision is made for mounting the brake mechanism directly upon the truck-frame of a two-wheeled truck and obviating the necessity of mounting a portion of the operative mechanism upon the bottom of the car, as commonly practiced, and which because of the motion between the ear and truck-frame disarranges the operative parts of the brake and renders them inoperative. l

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with the truck-frame of a car, of an independent supplementary eradle or frame attached thereto and projecting therefrom in a manner to support the brake mechanism beyond the end of the truck-frame proper, of the brakeapplying mechanism mounted upon said supplementary frame and connected with the brake-lever.

2. The combination with the truck-frame of a car, of the supplementary frame or cradle secured to the side bars of said frame and projecting therefrom at one end, the brake-operative mechanism mounted upon said supplementary frame, and means establishing a universal-joint connection between the powerapplying agent and the agent transmitting said power to the brakes.

In testimony whereof ,I sign this specification in the presence of two witnesses.
